HTML markup errors and warnings
(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Bad value “header1 rlogo” for attribute “id” on element “div”: An ID must not contain whitespace.
Element “option” without attribute “label” must not be empty.
Element “input” is missing required attribute “alt”.
Bad value “” for attribute “target” on element “a”: Browsing context name must be at least one character long.
Bad value “110px” for attribute “height” on element “img”: Expected a digit but saw “p” instead.
“"” in an unquoted attribute value. Probable causes: Attributes running together or a URL query string in an unquoted attribute value.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Element “param” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
Stray start tag “script”.
Cannot recover after last error. Any further errors will be ignored.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
